Splicing is a most important problem for single-mode fibres. 14). 14. Types of splice misalignment: (a) longitudinal, (b) tilt, (c) lateral offset. 15. Misalignment — transverse offset: (a) of two circular sections, (b) of two elliptic sections, (c) of circular and elliptic section. (Di Vita and Vannucci 1975, Gordon et al. 1977, Verrier and Goure 1987, Sakai and Kimura 1978). Let us consider the case of two identical step-index fibres carrying a beam of incoherent light. 15a).

Normalized spot size as a function of local V value along a taper for: (a) finite clad, step-profile fibre (solid line), (b) infinite parabolic profile (broken line) [After Henry and Love 1989]. 9. Normalized spot size as a function of distance along a linearly decreasing, finite clad, step-profile taper, showing: (a) adiabatic variation (broken line), (b) non adiabatic variation (solid line) [After Henry and Love 1989]. In the case of non adiabatic tapers the spot size is determined by the total field.
